FOCIL breakout hasn’t had a break since it started 8 months ago. We are continue working on rebasing onto Fulu, testing and adding metrics.
Rebase onto Fulu
Justin has rebased the CL spec onto Fulu. The CL spec will remain on top of Fulu and there will be a long-standing PR that rebases FOCIL onto Gloas. The latter will be updated regularly to stay ready for getting SFI’d.
Client implementations will rebase onto Gloas without ePBS implementation to minimize boilerplate code and remain as a feature fork. Specifically, our Kurtosis configs will set Gloas at epoch 0 and eip7805 fork at epoch 1.
Testing
Jihoon will publish a testing document that lays out test cases such as their inputs, outputs and coverage. In discussions with the Protocol Security and STEEL teams, we believe this will be invaluable.
Implementation Updates
- Geth has been updated to align with the revised Engine APIs spec.
- Lodestar has rebased onto Fulu and is implementing the updated CL, Engine APIs and Beacon APIs specs. Further testing and interop with the updated Geth will follow.
- Teku has rebased onto Fulu and will be working on the updated specs.
